4. INT register 1 and INT register 2
The INT register 1 is to set up the output of user-set frequency, or to set up alarm 1 interrupt. The INT register 2 is for
setting alarm 2 interrupt. Users are able to switch the output mode by using the status register 2. If selecting to use the
output mode for alarm interrupt by status register 2; this register works as the alarm-time data register. In the INT register
1, if selecting the output of user-set frequency by status register 2; this register works as the data register to set the
frequency for clock output. From the INT pin, a clock pulse and alarm interrupt are output, according to the or-condition
that these two registers have.
(1) Alarm interrupt
Users can set the alarm time (the data of day of the week, hour, minute) by using the INT register 1 and 2 which are
3-byte data registers. The configuration of register is as well as the data register of day of the week, hour, minute, in
the real-time data register; is expressed by the BCD code. Do not set a nonexistent day. Users are necessary to set
up the alarm-time data according to the 12/24 hour expression that they set by using the status register 1.

Figure 17 INT Register 1 and INT Register 2 (Alarm-Time Data)
The INT register 1 has A1WE, A1HE, A1mE at B0 in each byte. It is possible to make data valid; the data of day of the
week, hour, minute which are in the corresponded byte; by setting these bits to “1”. This is as well in A2WE, A2HE,
A2mE in the INT register 2.
Setting example: alarm time “7:00 pm” in the INT register 1
